D. genotypes
A. Phenotype
The physical expression --such as hair color -- is the result of the phenotype.
- The genotype is the basic genetic code.
- Allele are two or more alternative gene forms that generally arises via mutation, and
are located int eh same part of a chromosome.
- A gamete is a germ cell (female or male) that can unite wit the opposite sex germ cell
it eh process of zygote formation of sexual reproduction.
Which of the following does NOT produce hormones?

glands, adrenal glands, pancreas, ovaries, and testicles.
- They secrete hormones which help regulate mood, growth and development, tissue
function, metabolism, and sexual function and reproductive processes.

messages between he brain and the body.
Which organ is correctly matched with the cavity in which it is found?
A. spleen; pelvic cavity
B. brain; vertebral canal
C. bladder; abdominal cavity
D. heart; thoracic cavity
D. The heart is located in the thoracic cavity.
- The thoracic cavity extends from the neck to the diaphragm, which divides the
abdominal cavity from the thoracic cavity.
- Some of the major structures contained int he thoracic cavity are the ribs, heart,
lungs, mediastinum, trachea, and the esophagus.
- The spleen is located in the abdominal cavity.
- The brain is located in the cranial cavity.
- The bladder is located in the pelvic cavity.
A substance is considered acidic if it has a pH of less than which of the following?
,A. 12
B. 9
C. 7
D. 4
C. 7
The number of 7 is the "breaking point" between basic and acidic.
- above 7 solutions are considered basic
- below 7 solutions are considered acidic
- for instance, milk, with a pH of 6.5, is actually considered acidic.
- bleach, with a pH of 12.5, is considered basic
Which of the following choices best describes the location of the trachea in relation to
the esophagus?
A. lateral
B. anterior
C. posterior
D. dorsal
B. Anterior
The trachea is anterior or ventral to the esophagus.
, The trachea is separated from the esophagus by the epiglottis, which is a flap of

- the trachea's proximal portion is connected to the larynx and the distal portion splits
off into the right and left bronchi.
A triple beam balance would show the units of measurement in which form?
A. liters
B. grams
C. meters
D. gallons
B. Grams
All of the answers use the System of International Units (SI) of measurement with the
exception of gallons.
- A liter is the measurement of a liquid.
- Grams are a unit of measurement for the weight of an object, which would be
measured on the triple beam balance.
- Meters measure length.
Which of the following best describes a section that divides the body into equal upper
and lower portions?
A coronal
B. transverse
C. oblique
D. median
B. Transverse
The transverse plane separates the body into equal upper and lower portions.
- The oblique plane is when a cylindrical organ is sectioned with an angular cut across
the organ.
